Howard Hughes was a billionaire businessman, a pioneer of aviation, and an award-winning film producer. He developed the first "flying boat," the push-up bra, and the automatic hospital bed, and was adept at turning his hobbies into lucrative industries. Yet, despite all of his successes, he had no true friends or family. In the 1950s he became a recluse and was plagued by debilitating obsessive-compulsive disorders. In April 1976, after many years of drug abuse, Hughes slipped into a coma and died en route to a Houston hospital. This program, using archival footage and interviews with the few people who had contact with him, attempts to unravel some of the mysteries surrounding one of the richest men of the 20th century.
